On EVCP Info, it links related terminology to the relevant regulatory, standards or compliance framework used by UK-focused audiences.
B
Bidirectional Charging
Bidirectional charging allows energy to flow both into and out of an EV battery through compatible charging equipment. It is normally assessed alongside vehicle compatibility, export permissions, grid connection requirements and the supported communication standards.
P
Plug & Charge
Plug & Charge allows a compatible vehicle and charger to authenticate automatically through the charging connection without separate RFID or app steps. It is normally assessed alongside interoperability, supported protocol versions, firmware support and backend compatibility.
S
Smart Charging
Smart charging adjusts charging behaviour based on time, grid conditions, tariffs, user settings or available capacity. It is normally considered alongside charge point management systems, OCPP support, firmware updates, reporting and remote diagnostics.
V
Vehicle-to-Building (V2B)
Vehicle-to-Building allows an EV to supply energy to a building or site load through compatible bidirectional charging equipment. It is normally assessed alongside vehicle compatibility, export permissions, grid connection requirements and the supported communication standards.
Vehicle-to-Everything (V2X)
Vehicle-to-Everything (V2X) is an umbrella term for bidirectional EV charging use cases where energy can flow from the vehicle to another load, building, home, grid or wider energy system. It includes V2G, V2H, V2B and V2L depending on the destination of the exported energy.
Vehicle-to-Grid (V2G)
Vehicle-to-Grid allows an EV to export energy back to the electricity grid or support grid services through compatible charging equipment. It is normally assessed alongside DNO requirements, import/export limits, generation, storage and wider site energy management.
Vehicle-to-Home (V2H)
Vehicle-to-Home allows an EV to supply energy to a home through compatible bidirectional charging equipment and electrical controls. It is normally assessed alongside vehicle compatibility, export permissions, grid connection requirements and the supported communication standards.
